Update: You can use the keynote either to promote a new political talent or to showcase a dynamic speaker who can use the time to sell the party’s message ahead of the election (or, in the case of someone like Obama, both). Jindal fits the bill on the first point, but as much as it pains me to say it, the best we can do on the second is probably Huckabee. He’s not popular enough within the party to get the slot, in all likelihood, but there’s no better communicator on the right at the moment and it’d be a sop to evangelicals miffed at the fact that he’s left off the ticket. Worth considering.
